I lost 2 nice fish this winter because my fluorocarbon leader broke. That stuff has less stretch and is more brittle than conventional mono, and so it will be more likely to break on a fast-running fish.

Of course, I was using FC "mainline" material for my leader, as opposed to FC that was specially made as "leader" material. The FC leader material might be more durable and have more shock-absorbency, but I am not taking any more chances. I ditched my FC and moved to 20lb test leader. laugh

Of course, it could have been my incompetent fishing that caused the break offs... confused
